streak of light/object moved across the sky at an extremely high speedWhile driving west on rt 18 I saw a straight line streak of red light that flashed from north to south. The streak had a bearly visible beginning and end as if an object went by. This appeared to occur about 50 miles above our western horizon at an angle of about 60 degrees altitude, and moved through the sky covering a distance of about 50 degrees arc. It happewned so fast that I wasn't sure I saw it because of the tremendous speed. So I turned to my wife and said "did you see that?". She said "yes, what was that?". I asked "well what did you see?" She sais "a streak of light". The weather that night was 'electric' with lightning flashes lighting up the sky all around us as we travelled. All of these flashes were behind the clouded skys and bright white. I know what lightning looks like, after living in south Florida for five years, and seeing different types of lightning for fifty-six years. This was not lightning, but something moving at a major portion of the speed of light. Meteor? Not below the clouds moving that fast.
